Freescale vs Chipcon 802.15/Zigbee xcvr

Just wondering - has there been significant testing / comparison between 
Chipcon and Freescale 802.15 transceivers? Which has the better RF 
performance?
Any other features that stand out between the two?

They seem similar to the naked eye..

thanks

All I've found is

The Chipcon & Ember 2420 parts should have the same data, as they are
actually the same silicon.

The Freescale 2.4 GHz transmit/receive circuitry is more complex, so
there is slightly greater scope for errors in the PCB design & product
manufacture.

Now that Chipcon has bought Figure8, will Freescale continue to
license the Zigbee software from their competitor?

From a support point of view, I'd worry about Freescale.  We were
initially interested in their products and found that they would not
return our (several) queries and calls.   Small companies & start-ups need
not apply, I guess.
